you should probably have a general mechanism at the highest level to
trap any uncaught errors.

Eg in your top level script you should have something that prints out
the traceback.

typically

try:
        print getresult()
except:
        print "content-type: text/html"
        print
        print "<html><head><title></title></head><body>"
        print "<h1>An Error Occurred.</h1>"
        print "<pre>"
        import traceback
        traceback.print_exc()
        print "</pre>"
        print "</body></html>"

any error in the whole process wil result in a traceback being produced.
In this case I suspect that gadfly is not importable in the runing
context. To discover why you can import sys and print out sys.path etc
in the sectuon after the print "<pre>" above.
